Abstract:

Modern computing environments strive to be robust and reliable, and at the same time, aim at providing enough flexibility to an interactive user to edit, debug, and test programs easily and efficiently. Strongly typed languages satisfactorily meet the former goal by guaranteeing that type-consistent programs will not incur run-time type-errors. But most programming environments for such languages have to sacrifice the flexibility of interactive and incremental program development in order to achieve this consistency over the whole program. The problem is further complicated by the presence of polymorphism in many of these languages, where the definition of type- consistency is one of inclusion, rather than equality. Author
